Pediatric Endoscopy in Asia Pacific: Report from the Asian Pan-Pacific Society for Pediatric Gastroenterology Hepatology and Nutrition

Purpose

Pediatric gastrointestinal (GI) endoscopy significantly contributes to the diagnosis and management of GI diseases in children. Global data on pediatric GI endoscopy in the Asia-Pacific region are limited. We aimed to report the findings of a regional survey on pediatric endoscopy in the Asia-Pacific region.

Methods

A questionnaire-based survey involving GI endoscopy centers in 13 Asia-Pacific countries (June to November 2021). The questionnaires included annual procedure volumes (from basic diagnostics to advanced therapeutic endoscopy), endoscopists, sedation procedures, and national training programs.

Results

A total of 162 GI endoscopy centers completed the survey. All centers performed basic endoscopies (esophagogastroduodenoscopy and ileocolonoscopy); however, 45.1% and 59.1% of the centers performed less than 50 esophagogastroduodenoscopies and ileocolonoscopies per year, respectively. Small bowel evaluation (capsule endoscopy or balloon-assisted enteroscopy) was performed in 59.3% of the centers. Foreign body removal, polypectomy, and percutaneous endoscopic gastrostomy were performed in 89.5%, 85.8%, and 52.5% of centers, respectively. Endoscopic hemostatic interventions, which are life-saving procedures, included glue injection (30.9%), hemostasis of nonvariceal bleeding (65.4%), and endoscopic variceal ligation (70.4%). Pediatric GI endoscopy is performed not only by pediatric gastroenterologists but also by adult gastroenterologists in 21-50% of centers for many kinds of procedures. Sedation was provided by anesthesiologists in 65.4% of the centers. Most centers offer both adult and pediatric endoscopy training.

Conclusion

The study highlights regional disparities in pediatric GI endoscopy services. It emphasizes the need for expanded pediatric GI training and improved access to therapeutic endoscopy, particularly for life-saving procedures.

Identification of Iatrogenic Perforation in Pediatric Gastrointestinal Endoscopy

OBJECTIVES

Iatrogenic viscus perforation in pediatric gastrointestinal endoscopy (GIE) is a very rare, yet potentially life-threatening event. There are no evidence-based recommendations relating to immediate post-procedure follow-up to identify perforations and allow for timely management. This study aims to characterize the presentation of children with post-GIE perforation to better rationalize post-procedure recommendations.

METHODS

Retrospective study based on unrestricted pooled data from centers throughout Europe, North America, and the Middle East affiliated with the Endoscopy Special Interest Groups of European Society for Paediatric Gastroenterology Hepatology and Nutrition and North American Society for Pediatric Gastroenterology Hepatology and Nutrition. Procedural and patient data relating to clinical presentation of the perforation were recorded on standardized REDCap case-report forms.

RESULTS

Fifty-nine cases of viscus perforation were recorded [median age 6 years (interquartile range 3-13)]; 29 of 59 (49%) occurred following esophagogastroduodenoscopy, 26 of 59 (44%) following ileocolonoscopy, with 2 of 59 (3%) cases each following balloon enteroscopy and endoscopic retrograde cholangiopancreatography; 28 of 59 (48%) of perforations were identified during the procedure [26/28 (93%) endoscopically, 2/28 (7%) by fluoroscopy], and a further 5 of 59 (9%) identified within 4 hours. Overall 80% of perforations were identified within 12 hours. Among perforations identified subsequent to the procedure 19 of 31 (61%) presented with pain, 16 of 31 (52%) presented with fever, and 10 of 31 (32%) presented with abdominal rigidity or dyspnea; 30 of 59 (51%) were managed surgically, 17 of 59 (29%) managed conservatively, and 9 of 59 (15%) endoscopically; 4 of 59 (7%) patients died, all following esophageal perforation.

CONCLUSIONS

Iatrogenic perforation was identified immediately in over half of cases and in 80% of cases within 12 hours. This novel data can be utilized to generate guiding principles of post-procedural follow-up and monitoring.

PLAIN LANGUAGE SUMMARY

Bowel perforation following pediatric gastrointestinal endoscopy is very rare with no evidence to base post-procedure follow-up for high-risk procedures. We found that half were identified immediately with the large majority identified within 12 hours, mostly due to pain and fever.

A journey towards pediatric gastrointestinal endoscopy and its training: a narrative review

Background and aims

Gastrointestinal (GI) endoscopy in pediatric setting has unique features and, therefore, requires an approach that is tailored to pediatric practice. There is still heterogeneity between training programs worldwide in terms of duration, number of procedures and assessment during and at the end of the training process.

Methods

We conducted a narrative review aiming to describe and summarize the existing literature on the various training methods for pediatric GI endoscopy to highlight the significance of specific pediatric endoscopy training.

Results

Simulation-based tools have been implemented in several training programs, providing a safer learning environment for trainees, especially in their earlier stages of training. Assessment of competence is gradually shifting from the sole evaluation of procedural numbers towards the development of more reliable and valid tools that can accurately measure technical competence. Despite such seismic shift, there is still a need for a standardized and comprehensive pediatric-oriented endoscopy curriculum that incorporates acquisition of procedural skills education and is built on the current competency-based model of training. All the above must sink their roots in trainees and to ensure that the endoscopists of tomorrow are capable of delivering high quality of care for children undergoing endoscopy.

Conclusion

It is crucial to parallelly focus on the way trainers teach trainees. In this context, the implementation of "train the trainers" courses has improved important quality meters in GI endoscopy. Future research should put the focus on the potential subsequent favorable benefits of these changes on child health.

Approach to Endoscopic Balloon Dilatation in Pediatric Stricturing Crohn Disease: A Position Paper of the Endoscopy Special Interest Group of ESPGHAN

Crohn disease (CD) is often complicated by bowel strictures that can lead to obstructive symptoms, resistant inflammation, and penetrating complications. Endoscopic balloon dilatation of CD strictures has emerged as a safe and effective technique for relieving these strictures, which may obviate the need for surgical intervention in the short and medium term. This technique appears to be underutilized in pediatric CD. This position paper of the Endoscopy Special Interest Group of European Society for Pediatric Gastroenterology, Hepatology and Nutrition describes the potential applications, appropriate evaluation, practical technique, and management of complications of this important procedure. The aim being to better integrate this therapeutic strategy in pediatric CD management.

Paediatric gastrointestinal endoscopy in the Asian-Pacific region: Recent advances in diagnostic and therapeutic techniques

There has been a rapid expansion in the knowledge of paediatric gastroenterology over the recent decade, with a fast-growing repertoire of diagnostic techniques and management strategies for a wide spectrum of childhood gastrointestinal (GI) diseases. Paediatric GI endoscopy is a core competency every paediatric gastroenterologist should possess, and represents one of the most common procedures performed in children for both diagnostic and therapeutic purposes. Yet there remains a dearth of literature on the utility and outcomes of paediatric GI endoscopy in the Asia-Pacific region. Data on the diagnostic value of paediatric GI endoscopy would be an important aspect of discussion, with the emergence of inflammatory bowel disease (IBD) and eosinophilic GI disease as increasingly common endoscopic diagnoses. Time-based trends in paediatric GI endoscopy do point towards more IBD and gastroesophageal reflux disease-related complications being diagnosed, with a declining incidence of GI bleeding. However, the real-world diagnostic value of endoscopy in Asia must be contextualised to the region-specific prevalence of paediatric GI diseases. Helicobacter pylori infection, particularly that of multidrug-resistant strains, remains a highly prevalent problem in specific regions. Paediatric functional GI disorders still account for the majority of childhood GI complaints in most centres, hence the diagnostic yield of endoscopy should be critically evaluated in the absence of alarm symptoms. GI therapeutic endoscopy is also occasionally required for children with ingested foreign bodies, intestinal polyposis or oesophageal strictures requiring dilation. Endoscopic haemostasis is a potentially life-saving skill in cases of massive GI bleeding typically from varices or peptic ulcers. Advanced endoscopic techniques such as capsule endoscopy and balloon-assisted enteroscopy have found traction, particularly in East Asian centres, as invaluable diagnostic and therapeutic tools in the management of IBD, obscure GI bleeding and intestinal polyposis. State of the art endoscopic diagnostics and therapeutics, including the use of artificial intelligence-aided endoscopy algorithms, real-time confocal laser endomicroscopy and peroral endoscopic myotomy, are expected to gain more utility in paediatrics. As paediatric gastroenterology matures as a subspecialty in Asia, it is essential current paediatric endoscopists and future trainees adhere to minimum practice standards, and keep abreast of the evolving trends in the diagnostic and therapeutic value of endoscopy. This review discusses the available published literature on the utility of paediatric GI endoscopy in Asia Pacific, with the relevant clinical outcomes.

Upskilling Pediatric Ileocolonoscopy

Upskilling in ileocolonoscopy is an important aspect of pediatric endoscopic practice as it enables endoscopists to learn additional skills through education and training to improve outcomes. With the advent of technologies, endoscopy is continuously evolving. Many devices can be applied to improve endoscopy quality and ergonomics. In addition, techniques such as dynamic position change can be employed to increase procedural efficiency and completeness. Key to upskilling is enhancing endoscopists' cognitive, technical and nontechnical skills and the concept of "training the trainer" to ensure trainers have the requisite skills to teach endoscopy effectively. This chapter details aspects of upskilling pediatric ileocolonoscopy.

A 2-week intensive gastrointestinal endoscopy training program for pediatricians

BACKGROUND

In Japan there are limited opportunities for pediatricians to learn gastrointestinal (GI) endoscopy. This study investigated whether a short-term intensive training for 2 weeks in an adult GI setting enabled pediatricians to acquire basic technical competence for pediatric GI endoscopic procedures.

METHODS

This was a retrospective case series of pediatricians who underwent 2 weeks of intensive endoscopy training at an adult endoscopy unit in a community hospital. The numbers of esophagogastroduodenoscopy (EGD) and ileocolonoscopy procedures each pediatrician performed were evaluated. All enrolled pediatricians were asked to answer questionnaires regarding the 2 week intensive GI endoscopy training program.

RESULTS

There were 17 enrolled pediatricians, of whom 13 were men; average age 32 years (range 27-54). The median (range) numbers of EGDs and ileocolonoscopies performed by each pediatrician during the 2-week training period were 102 (66-144) and 14 (1-48), respectively. Fifteen out of 17 pediatricians experienced more than 100 GI endoscopies during the 2 weeks. All pediatricians performed biopsies as part of some EGD procedures. All 17 pediatricians found this program satisfactory. All pediatricians became cable of performing pediatric EGD (i.e., for children ≤15 years) after this training program. Sixteen pediatricians have continued to perform pediatric GI endoscopy since this training program.

CONCLUSIONS

A short-term intensive training program for 2 weeks in an adult GI setting enabled pediatricians to acquire basic technical competence for pediatric endoscopic procedures.

Pediatric endoscopy training across Europe: a survey of the ESPGHAN National Societies Network 2016-2019

Background and study aims  The ability to perform endoscopy procedures safely and effectively is a key aspect of quality clinical care in Pediatric Gastroenterology, Hepatology and Nutrition (PGHN). The aim of this survey, which was part of a global survey on PGHN training in Europe, was to assess endoscopy training opportunities provided across Europe. Methods  Responses to standardized questions related to endoscopy training were collected from training centers across Europe through the presidents/representatives of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition National Societies from June 2016 to December 2019. Results  A total of 100 training centers from 19 countries participated in the survey. In 57 centers, the endoscopy suit was attached to the PGHN center, while in 23, pediatric endoscopies were performed in adult endoscopy facilities. Ninety percent of centers reported the availability of specialized endoscopy nurses and 96 % of pediatric anesthetists. Pediatric endoscopies were performed by PGHN specialists in 55 centers, while 31 centers reported the involvement of an adult endoscopist and 14 of a pediatric surgeon. Dividing the number of procedures performed at the training center by the number of trainees, ≤ 20 upper, lower, or therapeutic endoscopies per trainee per year were reported by 0 %, 23 %, and 56 % of centers, respectively, whereas ≤ 5 wireless capsule endoscopies per trainee per year by 75 %. Only one country (United Kingdom) required separate certification of competency in endoscopy. Conclusions  Differences and deficiencies in infrastructure, staffing, and procedural volume, as well as in endoscopy competency assessment and certification, were identified among European PGHN training centers limiting training opportunities in pediatric endoscopy.

Colonoscope "Looping" During Ileo-Colonoscopy in Children is Significantly Different to that Observed in Adult Practice

OBJECTIVES

Ileo-colonoscopy (IC) can be technically challenging because of unpredictable colonoscope loop formation. Aims of this study were to assess the risk of loop formation and to attempt to understand which factors were likely to predispose to which subtype of loop.

METHODS

Prospective study conducted on children referred for an IC at Sheffield Children's Hospital. Presence and type of loop was objectively assessed using the magnetic endoscope imaging tool.

RESULTS

Three hundred procedures were prospectively evaluated. Only 9% of paediatric ICs were loop-free. Alpha loops were the most common loop in children older than 5, whereas reverse alpha loops and a wider variety of complex and repetitive loops were observed in younger patients. Once a specific type of loop has formed, the risk of re-looping in a different way or in a different position of the colon is reduced. Left lateral starting position was found to increase the risk of reverse alpha loops and re-looping. Challenging loops, such as reverse alpha, were more frequent in males. Higher body mass index (BMI) was associated with an increased risk of alpha and deep transverse loops formation, while lower BMI with a higher incidence of reverse alpha and N loop. Loop formation did not prevent 100% ileal intubation.

CONCLUSIONS

This study represents the first attempt to describe loop formation according to patient characteristics in a large paediatric series. Further studies are needed in order to establish if these findings could be helpful in simplifying the execution of IC procedures in children and facilitate the learning curve during endoscopy training programs.

Pediatric Endoscopy Quality Improvement Network Quality Standards and Indicators for Pediatric Endoscopists and Endoscopists in Training: A Joint NASPGHAN/ESPGHAN Guideline

INTRODUCTION

High-quality pediatric endoscopy requires reliable performance of procedures by competent individual providers who consistently uphold all standards determined to assure optimal patient outcomes. Establishing consensus expectations for ongoing monitoring and assessment of individual pediatric endoscopists is a method for confirming the highest possible quality of care for such procedures worldwide. We aim to provide guidance to define and measure quality of endoscopic care for children.

METHODS

With support from the North American and European Societies of Pediatric Gastroenterology Hepatology and Nutrition (NASPGHAN and ESPGHAN), an international working group of the Pediatric Endoscopy Quality Improvement Network (PEnQuIN) used the methodological strategy of the Appraisal of Guidelines for REsearch and Evaluation (AGREE) II instrument to develop standards and indicators relevant for assessing the quality of endoscopists. Consensus was sought via an iterative online Delphi process and finalized at an in-person conference. The quality of evidence and strength of recommendations were rated according to the GRADE (Grading of Recommendation Assessment, Development, and Evaluation) approach.

RESULTS

The PEnQuIN working group achieved consensus on 6 standards that all providers who perform pediatric endoscopy should uphold and 2 standards for pediatric endoscopists in training, with 7 corresponding indicators that can be used to identify high-quality endoscopists. Additionally, these can inform continuous quality improvement at the provider level. Minimum targets for defining high-quality pediatric ileocolonoscopy were set for 2 key indicators: cecal intubation rate (≥90%) and terminal ileal intubation rate (≥85%).

DISCUSSION

It is recommended that all individual providers performing or training to perform pediatric endoscopy initiate and engage with these international endoscopist-related standards and indicators developed by PEnQuIN.

Short-term intensive gastrointestinal endoscopy training program

BACKGROUND

In Japan there are limited opportunities for pediatric gastrointestinal (GI) trainees to learn GI endoscopy. This study investigated whether a short-term intensive training for 3 months in an adult GI unit enabled pediatric GI trainees to acquire the required number of cases and the technical competence to perform pediatric GI endoscopic procedures.

METHODS

This was a retrospective case series of pediatric GI trainees who underwent 3 months of intensive endoscopy training, which also included direct observation and a questionnaire. The numbers of esophagogastroduodenoscopies (EGD), ileocolonoscopies, and snare polypectomies each trainee performed as well as cecal intubation rates were collected with the goal of meeting the standards of overseas educational guidelines. The trainees were also asked about continuing experience with pediatric endoscopic procedures after the intensive training.

RESULTS

There were 10 enrolled trainees, 9 men, average age, 34 (range, 29-41). The average number (range) of EGD and ileocolonoscopies that the 10 trainees had done before this training period was 52 (0-200) and 15 (0-20), respectively. The average number (range) of EGD, ileocolonoscopies and snare polypectomies per each trainee was 651.7 (485-814), 159.2 (130-195) and 25.8 (10-55), respectively, over 3 months: all trainees thus fulfilled all of the criteria of the minimal training requirements. All trainees also reached the required threshold in the cecal intubation rate (>90%). In addition, all trainees were able to perform pediatric endoscopic procedures alone after the intensive training period.

CONCLUSIONS

Short-term intensive training for 3 months in an adult GI setting enabled pediatric GI trainees to acquire technical competence for pediatric endoscopic procedures.

Endoscopic retrograde cholangiopancreatography and endoscopic ultrasound in children

Gastrointestinal endoscopy is fundamental to diagnostic and therapeutic procedures in pediatric gastroenterology. In the decades since endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) for hepatobiliary and pancreatic disease were introduced into clinical practice, there has been increasing interest in these procedures, and practice guidelines and position papers that clearly define the role of ERCP and EUS in children have been published. Based on the distinction of endoscopy between children and adults, this review focuses on the current state of ERCP and EUS procedures in children, including the types of endoscopes used in children, general anesthesia and radiation exposure, biliary and pancreatic indications, considerations of education and training for ERCP and EUS procedures in children, and expectations for development of endoscopes for children.

Understanding and Responding to the Impact of COVID-19 on Paediatric Gastroenterology Training & Practice of Young ESPGHAN Members

OBJECTIVES

Limited data exist about the impact of the coronavirus disease 2019 (COVID-19) pandemic on the training and clinical practice of young doctors. The aim of this study was to evaluate the impact on paediatric gastroenterologists in training posts during the first wave of the European COVID pandemic.

METHODS

All Young members of European Society for Paediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) (YE) members received a multiple-choice questionnaire concerning the impact (if any) on their clinical practice, mental health, quality of care provided and fellowship/training experience. The survey was conducted between May 22, 2020 and June 10, 2020.

RESULTS

Of the 144 responders (40% of YE members), 85% (n = 123) reported an impact of COVID-19. Ninety-six percent reported an impact on their clinical practice, including more virtual patient consultation (n = 91), underutilization of ambulatory care (n = 113) and reduced or lack of planned admissions (n = 75). Endoscopy restrictions to semi-urgent or emergency cases were reported in 82 and lack of medical equipment/drugs (n = 47) were also reported.Reported adverse mental health issues included poor concentration, increased stress levels, an impact on family life in 62% and a reduced quality of care in 45%; this was more often reported in doctors from Southern Europe (54%) than in those from other geographical areas.Seventy-seven percent reported an impact on the content of their fellowship, including lack of participation in national/international meetings, withdrawn research time and limited mentoring.

CONCLUSIONS

The impact of the COVID-19 pandemic has been shown to affect the clinical practice, training and mental health of YE members. Adaptations of training programmes and targeted strategies to improve the clinical practice of young practitioners are needed and proposed in this manuscript.

Gastrointestinal endoscopy in children and adults: How do they differ?

Gastrointestinal endoscopy has grown dramatically over the past century, and with subsequent improvements in technology and anaesthesia, it has become a safe and useful tool for evaluation of GI pathology in children. There are substantial differences between paediatric and adult endoscopy beyond size, including: age-related patho-physiology and the different spectrum of diseases in children. Literature on endoscopic procedures in children is sparse but significant. The present review aims at describing the current knowledges on paediatric endoscopy practice and highlights the main areas of differences between paediatric and adult practice.

The Roles of Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography in the Evaluation and Treatment of Chronic Pancreatitis in Children: A Position Paper From the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition Pancreas Committee

INTRODUCTION

Pediatric chronic pancreatitis is increasingly diagnosed. Endoscopic methods [endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreatography (ERCP)] are useful tools to diagnose and manage chronic pancreatitis. Pediatric knowledge and use of these modalities is limited and warrants dissemination.

METHODS

Literature review of publications relating to use of ERCP and EUS for diagnosis and/or management of chronic pancreatitis with special attention to studies involving 0--18 years old subjects was conducted with summaries generated. Recommendations were developed and voted upon by authors.

RESULTS

Both EUS and ERCP can be used even in small children to assist in diagnosis of chronic pancreatitis in cases where cross-sectional imaging is not sufficient to diagnose or characterize the disease. Children under 15 kg for EUS and 10 kg for ERCP can be technically challenging. These procedures should be done optimally by appropriately trained endoscopists and adult gastroenterology providers with appropriate experience treating children. EUS and ERCP-related risks both include perforation, bleeding and pancreatitis. EUS is the preferred diagnostic modality over ERCP because of lower complication rates overall. Both modalities can be used for management of chronic pancreatitis -related fluid collections. ERCP has successfully been used to manage pancreatic duct stones.

CONCLUSION

EUS and ERCP can be safely used to diagnose chronic pancreatitis in pediatric patients and assist in management of chronic pancreatitis-related complications. Procedure-related risks are similar to those seen in adults, with EUS having a safer risk profile overall. The recent increase in pediatric-trained specialists will improve access of these modalities for children.
